For the future of the planet: DuPont promotes the bioplastic packaging program

DuPont of Wilmington, Germany, predicts that the use of high-performance bioplastics in the packaging industry or in other applications such as textiles and engineering plastics is very promising for the planet's environmental protection.

The above idea is not a trivial matter, it just highlights the milestone growth that a company already has and is documented. For example, the company's ground-breaking Bio-PDO compounds transform previous chemical processes into eco-efficient biochemical processes. DuPont is committed to innovative biomaterials that are designed to revolutionize the field of materials development, especially in the packaging industry. In March of this year, DuPont continued to work on the development of innovative biomaterial solutions, so it was also awarded the “Best Biomaterials Company of the Year” by the research firm Frost & Sullivan.

Information about "Plastic" can be found at Dr. Michael Saltzberg, Head of Global Biomaterials, DuPont Industrial Biosciences.

Michael Saltzberg says: Innovations in biomaterials can take the form of process innovations to make the same products or molecules in a more environmentally friendly way, or to develop new materials with superior technical performance compared to existing petroleum-based materials. We define “performance-based innovation” as the use of more environmentally friendly processes and more environmentally friendly materials to create better, innovative products.

At the same time, Michael Saltzberg also pointed out that one of the "Holy Grail" of plastic packaging is a viable passive solution. Not only does it make plastic packaging lightweight, but it also extends plastic packaging to applications where metal or glass packaging is currently required due to certain limitations.

In this new material, our company has a strong research interest in the converter and polymer brands, and we are currently signing a confidential joint development agreement with major potential customers.

Bio-PDO is a molecule called 1,3-propanediol produced using DuPont's proprietary fermentation process. Sorona is DuPont's brand name for polymers made from Bio-PDO and terephthalic acid; Sorona's generic name is triexta, which is used in textiles and carpets.

Michael Saltzberg commented that DuPont's process for producing Bio-PDO has been patented, but the molecule itself is not a patent of the company. Compared to other polymers, Sorona is a polymer with unique properties and properties. In some applications, especially in carpets, it is comparable to the superior properties of nylon; in other applications, Sorona is comparable to the performance of other synthetic fibers and the performance of natural fibers.

In addition, Bio-PDO is a liquid made from industrial corn sugar using a fermentation process. Sorona is a polymer made from Bio-PDO and terephthalic acid, which is derived from petroleum. Sorona is typically supplied to customers as polymer pellets that can be extruded into fibers, films and molded parts.

For packaging applications, DuPont is working with Archer Daniels Midland to develop a new monomeric methyl furancarboxylate (FDME). When combined with Bio-PDO or other monomers to form a polymer, FDME provides a particularly suitable for beverage and food packaging and has breakthrough barrier properties for carbon dioxide and oxygen.

For packaging, Sorona has some limitations in the application of thin films. For the development of FDME, DuPont is working with Archer Daniels Midland to build a demonstration plant that will be available in the fourth quarter of this year. If the project is still in progress, we expect the commercial plant to be completed and put into production in 2021.

Michael Saltzberg said: We expect that furan-based polymers made by FDME will be used in hard packaging applications where good barrier properties of carbon dioxide and oxygen are important, including carbonated soft drinks, beer, carbonated water. And fresh juices, etc. We also expect FDME to be used in film-based applications where barrier properties are critical, such as in the meat and cheese packaging sector.

In addition, the development of FDME and polymers made from it is DuPont's next step in the field of biomaterial packaging. We are promoting the commercialization of this material and look forward to its further development. Despite a lot of work to do now and in the future, DuPont is working hard to promote commercialization in 2021.
